The Murata Power Solutions NCS3S4803SC is a member of the NCS3 series of isolated 3W DC-DC converters. It accepts a wide 4:1 input voltage range of 18V to 80V (48V nominal) and delivers a single regulated 3.3V output at up to 700mA (2.31W). The converter provides 1500VDC input-to-output isolation, making it suitable for applications requiring galvanic isolation.
Key electrical specifications include typical efficiencies of 70% to 74% at 12V or 48V input and 74% to 77% at 24V input. Output voltage set point accuracy is ±1% typical, with line regulation of ±0.5% and load regulation of ±1%. Ripple and noise is typically 22mVp-p (55mVp-p maximum) at 20MHz bandwidth. The module includes continuous short circuit protection and a control pin for remote on/off.
The NCS3S4803SC is packaged in an 8-DIP through-hole module measuring 22.0mm x 9.5mm x 11.3mm. It operates over a -40°C to +85°C temperature range with derating. The design uses no electrolytic capacitors, enhancing reliability. Typical applications include telecommunications, battery-powered systems, process control, and distributed power architectures.
